What it is
The Grant MPCBS70 is a 14 litre expansion vessel used on Grant Vortex Pro 36E Combi condensing boilers. It absorbs the volume increase of the sealed heating system water as it heats, limiting pressure rise and protecting the boiler and system components. It is fitted to both internal and external combi variants of the 36E.
Signs this part needs replacing
- System pressure rises sharply when the boiler heats up and falls again once it cools.
- The boiler loses pressure repeatedly and needs frequent topping up.
- Water discharges from the pressure relief valve during normal operation.
- The vessel feels heavy or full of water when tapped, indicating a failed internal diaphragm.
- Corrosion or water staining is visible around the vessel connection or shell.
Before you order
- Confirm the boiler is a Grant Vortex Pro 36E Combi and note whether it is the internal or external model.
- Check the capacity and part number marked on the existing vessel before ordering.
- Verify the system has been depressurised and drained to the level required for safe removal.
- Check the vessel connection and available clearance match the installation position on your appliance.
